Ken: Yes we have been using RG400 which is stranded rather than solid conductor of RG142.  They are both double shielded. https://www.awcwire.com/allied-university/this-vs-that/rg142-vs-rg400 We only use RG214 for short outdoor jumpers for antenna connections to LDF4-50 hardline which is lower loss and much cheaper than RG214. We have been getting indoor jumper cables from https://www.coaxrf.com/product-category/1-rf-coaxial-cables/ for several years.  They seem to be built well, they can produce any length or combination of connectors and they ship the next day for free and I usually get it overnight, they are in Valencia. The cost is just about the cost of the materials. Wayne On 1/13/2025 10:24 PM, WILLIAM TALANIAN via SBARC-list wrote:

Ken,

Saw the error and thought it was a new type.Emoji

Why bother  making up jumpers. The factory made ones that Wayne got we well made and reasonable considering parts.

Get the company name from Wayne.

Correction: The correct cable I'm after is "MIL-17-C RG-142". Thanks. Ken

I am going to build all new patch cables for the WB6OBB repeater system and I'm wondering if anyone has any surplus MIL-17-C RG-214 coax (or equivalent) laying around they would be willing to part with.  This is double shielded silver plated coax that is good for repeater systems in high-RF environments.

Thanks! Ken

Not a new type, actually, both exist.  They are both double shielded silver plated with PTFE dialectric (if you get the mil spec type).  The only difference I'm aware of is that the RG-214 is larger diameter than the RG-142 and I'd pulled the wrong number from my notes.  I could use either, but prefer the smaller diameter for flexibility (and possibly better availability and possibly lower cost of connectors).I looked into factory made but most vendors don't have the lengths I want so it becomes custom and with RG-214 prices were all $100 per assembly from just about any source.  Now that I am searching for RG-142 (instead) the price has gone down more than half so perhaps I'll order custom.  Wayne - would like to know where you've gotten in past, if you have had success with them.Ken--On Tuesday, January 14, 2025 6:24 AM +0000 WILLIAM TALANIAN via SBARC-list <sbarc-list@lists.netlojix.com> wrote:> Ken,>>> Saw the error and thought it was a new type.
